Low Stock Push Notifications: Never Run Out of Your Top 20 SKUs Again

The Stockout You Didn't See Coming#

Your best-selling protein powder has been on the shelf for three weeks. Sales have been steady. On a Saturday morning, a group of gym-goers comes in and three of them buy the last four units. By 11am, it's gone. You don't find out until your staff texts you at 2pm that "we've had five people ask for the vanilla protein today." You order Monday. It arrives Wednesday. You've lost two days of sales on your highest-margin product — and at least two of those customers went to your competitor across town and found out their loyalty card works there too.

Setting Reorder Points That Actually Work#

Most businesses set reorder points too late — "alert when stock = 0" means you're already out. A proper reorder point accounts for your average daily sales velocity and your supplier lead time. If you sell 8 units per day and your supplier takes 4 days to deliver, your reorder point is 32 units (8 × 4) plus safety stock (say, 16 units) = 48. AskBiz calculates this automatically based on your historical sales data — you don't need to work it out for every SKU. You just set the safety stock day cover you want (e.g. "2 days' safety stock") and AskBiz does the rest.

The Alert That Triggers Action#

At 10:47am on Saturday, your phone buzzes: "Low stock alert: Vanilla Protein 1kg (SKU VP1000) — 52 units remaining (4.2 days' supply). Reorder point: 48." You're not in the shop. You open AskBiz, see the alert, tap "Reorder" — a draft purchase order to your supplier pops up, pre-filled with quantity and price. You approve it. It emails to the supplier. You put your phone down. The order will arrive before you run out. Total time: 90 seconds. No phone call, no spreadsheet, no chance of forgetting.

Multi-Channel Stock Accuracy#

If you sell on Shopify as well as in-store, stock alerts are only useful if they reflect both channels. AskBiz syncs with Shopify in real time — every online sale reduces the same inventory pool your push notification is monitoring. If an online order takes your vanilla protein from 52 to 44 units while you're reviewing the alert, the alert updates. You're always looking at live inventory, not a snapshot from last night's import.

A Worked Example: Avoiding a Bank Holiday Stockout#

A convenience store owner set AskBiz reorder alerts on her top 25 SKUs ahead of a bank holiday weekend, when sales typically run 40% above a normal Saturday and suppliers are closed for an extra day. On the Thursday before, three alerts fired: soft drinks, bread, and charcoal were all tracking toward a stockout by Saturday afternoon based on the accelerated bank-holiday sales pace AskBiz was already picking up from that morning's trading. She placed emergency top-up orders with her supplier that same afternoon, well before their Friday cut-off. Without the alert, she'd have discovered the gap on Saturday at 2pm — exactly the point in previous years when she'd had to turn away customers on her three best-selling lines of the year.

Common Mistakes When Setting Reorder Points#

The most common mistake is setting one blanket reorder point across every product rather than basing it on each item's actual sales velocity and lead time — a slow-moving product and a fast-moving one need very different buffers. The second is not adjusting for seasonality: a reorder point calculated from average daily sales in a quiet month will be far too low heading into a busy one, which is exactly when a stockout costs the most. The third is ignoring supplier lead time volatility — if your usual two-day delivery sometimes stretches to four during holidays or bad weather, your safety stock buffer needs to reflect the worst case, not the average case, or the alert fires too late to matter.
